OE FRANKLIN, MASSACHUSETTS.

EXTENSION-TABLE.

Specification of Letters Patent.

Patented Dee. ML, 1915..

Application filed November 10, 1914. Serial No. 871,329.

To all whom it may concern:

Be it known that I, THnoDono MAIA, a subject of the King of Italy, residing at Franklin, in the county of Norfolk and State of lilassachusetts, have invented new and useful Improvements in Extension-Tables, of which the following is a specification.

My present invention pertains to endextension tables; and it consists in the simple, compact and strong construction hereinafter described and definitely claimed.

In the accompanying drawings, which are hereby made a part hereof: Figure 1 is a view, partly in elevation and partly in section, of so much of a table as is necessary to illustrate my invention, the table being shown in its contracted state. Fig. 2 is afragmentary elevation taken at a right angle to Fig. 1. Fig. 3 is a detail vertical section showing one of the extension leaves in its useful position. Fig. 4 is an inverted plan view showing the parts at one side of the main transverse bar, it being understood that the parts at the opposite side of said bar are similar in construction to the parts illustrated.

Similar letters of reference designate corresponding parts in all of the views of the drawings.

The main frame of the table comprises the conventional legs A and frame bars B, as illustrated. Fixed to the side bars B is a transverse bar C, in the underside of which is a groove, of dove-tail form in cross-section, Figs. 1 and 3, which groove extends in the direction of the length of the bar and is open at one end as appears in Fig. 4. Movable reetilinearly in the said groove is an operating bar 11, of clove-tail form in crosssection, that is equipped near the open end of the groove with a pivoted handle 0 hav ing a depending hand grasp 0. Fixed to the under side of the bar C and straddling the operating bar H is a fixture L for a purpose hereinafter set forth.

The bar C is rabbeted as appears in Fig. \1, and in the rabbets are normally arranged \lhie inner transverse edges of the main leaves which leaves are connected with the bar through the medium of flush hinges T or her suitable means.

Arranged under the leaves D and adapted be moved outwardly in an edgewise maner are auxiliary leaves E. These leaves E are never idle inasmuch as they serve when extended as auxiliary or extension leaves to ncrease the length of the table, and when in the position shown in Fig. 1 they support the leaves D and this in such manner that the table is provided with a double and exceedingly solid top. 7

Fixed to the underside of each extension leaf E is one or more, preferably two sup porting bars F which extend in the direction of the length of the table. Each of the said bars F is provided with a shoulder G, and each is of such length that when its comple Inentary leaf is in extended position, the .i

said shoulder G will bear solidly against the inner side of the adjacent frame bar l3, and the inner end of the said supporting bar F will bear against the underside of the transverse bar 0. From this it follows that the bars F complementary to each leaf E will strongly support the leaf when in the position shown in Fig. l and also when in the position shown in Fig. 8. It will also be manifest from Fig. 3 that when the leaves D are lowered to horizontal position at the inner edges of the leaves E, the intermediate portions of the bars F will solidly support the outer edges of the leaves D.

The bar H, its lever O and the fixture L are provided when it is desired to extend or retract the two leaves E simultaneously, and they are employed in connection with lazytongs M as clearly shown in Fig. 4:; the end members of the lazytongs being connected to the undersides of the leaves E as indicated by N and N, and intermediate members of the lazytongs being pivotally connected at I to the underside of the operating bar H, while other intermediate members of the lazytongs are connected in a pivotal manner to the fixture L as indicated by K. Thus it will be seen that when an operator grasps the handle 0 and draws the bar H outwardly into the position shown in Fig. 4, the leaves will be moved outwardly to the positions shown in Figs. 3 and l. It will also be understood that on inward movement of the bar H the lazytongs will be contracted and the leaves E will be retracted to the positions shown in Fig. 3. In this connection attention is directed to the fact that the leaves D are swung upwardly precedent to either adjustment of the leaves E, and that after the operating bar H is positioned as shown in Fig. tithe handle isswun'g under the table top, as shown by dotted lines in Fig. 4 so as to be out of the way. 7

Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. In an end extension table, the combina-w tion of a frame, an operating bar movable cross-wise of the frame and guided thereln, mam leaves arranged on the frame and hinged at their inner edges thereto, auxnation of legs, frame bars fixedly connected with said-legs, a transverse bar fixed to opposite frame bars and having a longitudinal groove in its underside, a fixture carried at the underside of-said bar and straddling said groove, an operating bar movable endwise in said groove, a handle pivoted to the outer end of said operating bar and arranged to swing horizontally, main leaves disposed at opposite sides of said transverse bar, auxiliary leaves movable to and from positions under the main leaves, supporting bars fixed to the undersides of the auxiliary leaves and having inclined lower edges arranged to ride on said framewbars; said supporting bars being provided with inner inclined edges adapted to rest under and support the outer edges of the main leaves, and lazytongshaving end members connected with the auxiliary leaves and also having intermediate members connected with the operating bar and the fixture at the under side of the transverse bar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

THEODORO MAIA. Witnesses:
